ROTARY AIR on FLUID COMPRESSOR.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, CHARLES A. KAIsER, a citizen of the United States, residing at Astoria, in'the county of Queens and State of New York, have invented new and useful Improvements in Rotary Air or Fluid Coinpressors, of which the following is a specification.

This invention resides in certainnovel features of-construction set forth in the followvalve-rods. Fig. 6 shows a side elevation of Big. 5.

In this drawing is shown a cylinder (1,

A drum or cylinder 12 rotates in contact with a packing (1.. This packing, of brass or other suitable material, can be set or adjusted by a screw or suitable means and is located between the inlet and outlet portions of the cylinder.

passing or forced along a channel or outlet attachment is strikes against bafliers 1, S0,. that oil or foreign matter is thrown off and lands in the separating chamber or reservoir n. The deflectors or bafl'lers m throw the air against or toward a diaphragm 0 or its rim or flange 0, so that foreign matter passing over onto diaphragm 0 passes thenceinto reservoir p, where it passes into the-reservoir 'n. A pipe or pipesg lead oil to the compressor or drum, so as to lubricate or pack the same or its bearings r. The baflilers lm are shown superposed and facing or inclined in opposite directions. Bafller l is tapered or directed down or into reservoir n, while baflier m is.directed in the opposite direction or upward; The reservoirs n p concentrically surround one another and the bafllers and communicate with one another, so that oil can pass from chamber 10 to chambern. The diaphragm 0 is supported on aflange extending about the interior of chamber 1). This dia hragm does not fit tight in the chamber,

an the diaphragm and the interior of the chamber being left rough or unfinished as these parts come from casting or from the foundry, the oil settling on part 0 will leak or pass down to pipe q. The under face of diaphragm 0 or 1ts contacting parts could also e channeled or roughened by file or other.

cuts to allow leakage or passage of oil, but usually the unfinished or rough condition of the casting will allow sufficient leakage. The

separatingchamber or chambers 7) and n 1 could be cast with conduit k or, suitably connected thereto.

The piston or plunger f can have the packing i adjusted to compensate for wear. By turning screws h so as to force the wedges in the proper direction the packing iscarried or forced to the c linder. Any suitable screw or adjusting evice can be provided .forthe packing. Suitable tool holes or openings t at the base of the cylinder head or cover give access to screws h for a screwdriver or instrument. Each screw h when moving inward will force its wedge it against rod 9 to move or setthe piston f with packing 6. Each iston is also shown with a screw 2, adapted to set the respective rod 9 or form an abutment for the rod in the piston. The d'ustability of the pistons on the rods provi es means to compensate for wear. The cylinder a is slotted or has openings at suita le points for air'or fluid to enter and leave at the inlet and outlet 11 and b. The connecting-rods g are made to firml connect or unite opposite pistons, so that t ey move in unison to be in tight contact with the inside of the cylinder without any spring being reuired for said valves. The oil delivered to t e bearing will pass along channel u to the drum and thence to the circumference thereofto the packing to lubricate and cause tight joints between the drum and cylinder. At one end of rods 9 are shown screws h and wedges h for adjusting to any extent required for compensating for shortness of the rod. One end of each rod is shown seatedagainst a screw 2. Before the parts are asquently called for. In other words, the screws 2 are used to set the rods in proper position for the Wedges h to be forced by screws h against the rods, and these screws h are readily accessible, as explained, on the S removal of cover. t; The wedges h, asthey are forced against the rods, will cause the pistons f to be spread or separated farther from one another, and consequently press against packing i, sitting against the inner wall of the cylinder.

The air from the intake 6 can be obtained in whole or in part froma conduit 3, which, extending along an end or both ends of the cylinder, will serve to cool the cylinder to some degree. I

What I claim as my invention, and desire to secure by Letters Patent, is' I 1. A blower or compressor comprising a fixed cylinder with inlet and outlet portions, a packing between said inlet and outlet, an

eccentrically-mounted rotary cylinder in permanent contact with the packing, diametrically-movable pistons in the rotary cylinder, and connecting-rods for the pistons, the latter being provided with adjusting-screws to set the same for maintaining permanent contact with the fixed cylinder during rotation the pistons having 0 enings giving access to the screws without ismounting the pa ts.

2. A blower comprising a cylinder, .a rotary drum with pistons, packings seated in the pistons and made to bear against the cylinder, connecting-rods extended into the istons, and screws in the pistons and we ges adapted to be forced by the screws against the rods to spread or move the pistons away from one another.

3. A blower comprising a cylinder, a rotary drum in the cylinder, pistons in the drum, connecting-rods made to terminate in the pistons, wedges in the pistons, and screws for forcing the wedges against the ends of the rods in the pistons to slide or spread the latter on the rods.

. 4. A blower comprising a cylinder, a rotary drum in the cylinder, pistons in the drum, rods on which the pistons are adjustably mounted, screws in the pistons m'ade to sit against one end of the rods and adjusting wedges and screws in the pistons for engaging the other ends of the rods, said pistons having openings giving access to the screws, and the cylinder having a tool-hole for allowing access to the pistons.

5. A blower comprising a cylinder, a rotary drum with oppositely-located sliding piston, rods extended into and made to rigidly abut against both pistons to reciprocate simultaneously with the same during the operation of t device, adjusting-screws made to sit rigidly against one end of the rods, and adjusting wedges and screws for acting against the other ends of the rods, said rods being smooth or unthreaded so as to be capable of being set or adjusted in the pistons by the adjusting screws and wedges.

In testimony whereof I have hereunto set my hand in the presence 9f two subscribing witnesses.
